Note
Low Risk
Low risk: CI/release workflow changes only, swapping tag-based action references for pinned SHAs; main risk is breakage if the pinned commits are incorrect or later revoked.
Overview
Pins third-party GitHub Actions used by the shared CI and publish composites and the
release-pleaseworkflow from floating tags (e.g.@v1,@v2,@v3) to full commit SHAs.This reduces supply-chain risk by ensuring CI/release runs use immutable action revisions, without changing the workflow logic or inputs.
